c656731901 video: Avoid using #ifdef in console_rotate.c
This code does not really need to use #ifdef. We can use if() instead and
gain build coverage without impacting code size.

Change the #ifdefs to use IS_ENABLED() instead.

2cc393f32f video: make BPP and ANSI configs optional
Many boards do not use all selected framebuffer depth
configurations, for such boards there is some unused
code in video and console uclass routines. Make depth
specific code optional to avoid dead code and slightly
reduce binary size. Also make ANSI code optional for
the same reason. When i.e. using only VIDEO_BPP16 the
code size shrinks (below values when using gcc-7.3.0):

754815b854 video: stm32: remove the compatible "synopsys, dw-mipi-dsi" support
Remove the compatible "synopsys,dw-mipi-dsi" added in U-Boot
(it don't exist in Linux kernel binding); it is only used
to bind the generic synopsys UCLASS_DSI_HOST "dw_mipi_dsi" to
the driver "stm32-display-dsi" UCLASS_VIDEO_BRIDGE

This binding is done in Linux kernel drivers without compatible
(dw_mipi_dsi_bind() is called in bind of driver, for example in
drivers/gpu/drm/rockchip/dw-mipi-dsi-rockchip.c).

This patch does the same in U-Boot driver, the STM32 driver
calls during its bind the function device_bind_driver_to_node
to bind the generic driver "dw_mipi_dsi" at the same address.

This patch reduces the device tree differences
between Linux kernel and U-Boot for stm32mp1 platform.

Tested with v2020.01-rc1 on STM32MP157C-EV1 and STM32MP157C-DK2.

The dependency of driver is clearer and the probe order is guaranteed.

ec3dcea744 video: mxsfb: Configure the clock after eLCDIF reset
Running stress reboot test on a i.MX6ULL evk board with a
custom LCD can lead to splash screen failure (black screen).

After comparing the eLCDIF initialization with the Linux kernel
driver, it was noticed that the eLCDIF reset is the first operation
that needs to be done.

So do like the eLCDIF Linux driver and move the eLCDIF clock
frequency configuration after the eLCDIF reset and just prior to
setting the RUN bit.

With this change applied, no more black screen issues has been
found during overnight reboot stress tests.

Fix this by using DIV_ROUND_UP to calculate the divider.  This works

never higher than the requested pixel clock.

eabb0725d4 video/console: Implement reverse video ANSI sequence for DM_VIDEO
The video console for DM_VIDEO compliant drivers only understands a very
small number of ANSI sequences. First and foremost it misses the "reverse
video" command, which is used by our own bootmenu command to highlight
the selected entry.

To avoid forcing people to use their imagination when using the
bootmenu, let's just implement the rather simple reverse effect. We need
to store the background colour index for that, so that we can
recalculate both the foreground and background colour pixel values.

When the character to be printed on a DM_VIDEO console is from the
"extended ASCII" range (0x80 - 0xff), it will be treated as a negative

Cast the character to an unsigned type to make the index always positive
and avoid an out-of-bounds access.

1feed358ed sunxi: video: HDMI: Fix clock setup
Currently, HDMI driver doesn't consider minimum and maximum allowed rate
of pll3 (video PLL). It works most of the time, but not always.

Consider monitor with resolution 1920x1200, which has pixel clock rate
of 154 MHz. Current code would determine that pll3 rate has to be set to
154 MHz. However, minimum supported rate is 192 MHz. In this case video
output just won't work.

The reason why the driver is written in the way it is, is that at the
time HDMI PHY and clock configuration wasn't fully understood. But now
we have needed knowledge, so the issue can be fixed.

With this fix, clock configuration routine uses full range (1-16) for
clock divider instead of limited one (1, 2, 4, 11). It also considers
minimum and maximum allowed rate for pll3.

e3245e4254 video: simplefb: Remove DM_FLAG_PRE_RELOC flag
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.

To mitigate this potential impact, the following changes are
implemented:

- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
  only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
  is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree

7d121a8ea4 sunxi: use 6MHz PLL_VIDEO step for DE2 for higher resolution LCD
DE2 SoCs can support LCDs up to 1080p (e.g. A64), and 3MHz step won't
let PLL_VIDEO be high enough for them.

Use 6MHz step for PLL_VIDEO when using DE2, to satisfy 1080p LCD.

8336a43792 dm: video: bridge: don't fail to activate bridge if reset or sleep GPIO is missing
Both GPIOs are optional, so we shouldn't fail if any is missing.
Without this fix reset is not deasserted if sleep GPIO is missing.

9949ee876d video: at91: Adjust vidconsole_position_cursor() to use char pos
At present this function uses pixels but it seems more useful for it to
position in terms of characters on the screen. This also matches the
comment to the function. Update this.

Unfortunately there is one user of this function (at91). Have a crack at
fixing this, since I cannot test it.

07bc873c73 ctags: Minor changes to fix ctags output
At present ctags emits lines with unmatched quotes which means that the
output file is invalid. This is with exuberant-ctags version 5.9~svn201103
but I also see it with plain ctags. I am not sure that it is a bug though.

Make a few minor changes in the source code to fix this problem.

a4f737a9c3 panel: Expand the backlight support
At present the panel can be turned on but not off, and the brightness
cannot be controlled at run-time. Add a new API function to both the panel
and backlight uclasses to handle this. Enhance the PWM backlight driver
to deal with custom levels properly and allow the backlight to be turned
on and off.

Update the test to cover thes new features.

55d39911c0 sandbox: video: Speed up video output
At present there are many situations where sandbox syncs the display to
the SDL frame buffer. This is a very expensive operation but is only
needed every now and then. Update video_sync() so that we can specify
whether this operation is really needed.

At present this flag is not used on other architectures. It could also
be used for reducing writeback-cache flushes but the benefit of that would
need to be investigated.
